警報電子郵件無法正常工作

我想在lastwritetime超過16分鐘時發送電子郵件。我想遍歷我的文件並檢查lastwritetime。超過16分鐘時發送電子郵件提醒。我正在尋找使用存儲圖像的本地或系統時間。我已經掌握了這一點，但系統電子郵件過於頻繁，在我運行測試並且圖像未更新時不會提示。我究竟做錯了什麼？警報電子郵件無法正常工作

try 
{ 
    string files = @"\\cyclops-ch2-10\users\!SptEntEng\Desktop\ScreenScrapes\ChicagoSkyvision\ScreenScrape\ScreenScrape.png"; 
    string files1 = @"\\cyclops-ch2-10\users\!SptEntEng\Desktop\ScreenScrapes\ChicagoSeachange\ScreenScrape\ScreenScrape.png";

    foreach (string file in FilePaths)

     if (fi.LastWriteTime < DateTime.Now.AddMinutes(16)) 
     { 
      client.Send(CyclopsCentral); 
      break; 
     } 
    }

這看起來與你的[前一個問題（https://stackoverflow.com/questions/45600276/email-alert-sends-email -when-lastwritetime-is-current） – stuartd

你調試過嗎？ – Harsh

可能重複[電子郵件警報當lastwritetime是當前發送電子郵件]（https://stackoverflow.com/questions/45600276/email-alert-sends-email-when-lastwritetime-is-current） –

當您比較未來時間時，您的支票將始終爲真。

if (fi.LastWriteTime < DateTime.Now.AddMinutes(16))

你需要改變它到-16

if (fi.LastWriteTime < DateTime.Now.AddMinutes(-16))

具有諷刺意味的是，在[相同的上一個問題]（https://stackoverflow.com/questions/45600276/email-alert-sends-email-when-lastwritetime-is-current）代碼**是**'DateTime.Now .AddMinutes（-16）' – stuartd
